Just copy your .config's somewhere else and copy them in place
whenever you want to build that configuration. This is pretty much
what the make <project>_defconfig make target does.

Also have a look at the make O=</path/to/build/in> support.

E.G. something like:

for project in projectA projectB projectC;
do
        cp configs/$project .config
        yes ''|make oldconfig
        make O=/tmp/build/$project
done

(the yes '' part is to accept the defaults for new configuration
options)
